AEM’s Analog-Style Wideband UEGO AFR Gauge is a wideband UEGO air/fuel ratio controller (AFR) and gauge in one. It unites accuracy, speed and control with an easy to read, digital LED display and sweeping LED “needle” that changes colors as AFR changes from rich to lean.
Our analog-style gauge-type controller features 320 degrees of resolution for detecting even a tenth of a point change in AFR, and has a high-speed electric stepper motor for lightning-fast needle movement. The Analog Wideband gauge also features seven (7) user-selectable back lighting colors that allow you to match it to most factory gauge clusters. As with all of our Wideband Systems, they are fast and accurate.
WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER?
AEM's Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced “You-Way-Go”) Controllers are powerful, cost effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of their engine.
WHY USE A WIDEBAND AIR/FUEL CONTROLLER?
Accurate AFR data is critical when tuning an engine. Running rich (very low air/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned.
WHAT IS FREE-AIR CALIBRATION?
Some of our competitors require that you frequently perform a free-air calibration procedure to calibrate their O2 sensors. This process involves removing the sensor from the bung while still connected to the controller device, then waving the sensor in the air so it can read atmospheric O2 levels. We use Bosch 4.2LSU sensors in our wideband controllers. Our sensors are individually laboratory-calibrated by Bosch and never require free air calibration!
CAN I CHANGE THE AEM UEGO SENSOR’S CONNECTOR?
No. There is a laser-etched, calibrated resistor in the sensor’s connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor’s output.
Our highly popular Analog-Style Wideband O2 air/fuel ratio UEGO gauge features a high-speed electric stepper motor for lightning-fast needle movement and a full 320 degrees of viewing resolution to detect even a .5 degree of change in AFR. Seven backlit colors allow you to match the lighting to most factory gauge clusters. A 52mm (2-1/16") gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM gauges feature a 0-5v analog output for use with data loggers and almost any engine management system.
The Analog-Style Wideband O2 air/fuel ratio UEGO gauge is a must if you want to maximize your engine's power and safety. When tuning an engine, accurate air/fuel ratio data is critical because running with too rich of an AFR can cause a loss of power, and running a lean AFR can result in serious engine damage. AEM's Analog-Style Wideband AFR UEGO gauge can quickly alert you to even a .1 change in air/fuel ratio and provide enough time to shut down an engine before damage occurs.
The Bosch UEGO sensor gives the controller its speed and accuracy. It is laboratory calibrated at the factory and NEVER requires free-air calibration when used with AEM wideband air/fuel controllers.
